Abu Ishaq says: I asked Sayyiduna Zaid bin Arqam (may Allah be pleased with him), "In how many battles did you participate with the Messenger of Allah (peace and blessings be upon him)?" He said, "In seventeen battles." And he narrated to me that the Messenger of Allah (peace and blessings be upon him) fought nineteen battles and performed one Hajj after migration, which is called the Farewell Hajj. (The narrator of the hadith) Abu Ishaq said that the Messenger of Allah (peace and blessings be upon him) performed another Hajj in Makkah (before migration).
